Description

Horizontal purifying air conditioner for operating room

Technical Field

The utility model relates to the field of medical equipment, in particular to a horizontal air conditioner that purifies for operating room.

Background

The clean operating room adopts an air purification technology, the total amount of microorganism particles and particles in the operating environment air is reduced to an allowable level, but the operating room has strong airtightness, poor air fluidity, small air volume, no window opening for a long time and insufficient sunlight, pathogenic microorganisms are easy to breed, and the requirement of indoor air quality on fresh air volume cannot be met. The aim of medical environment control is provided by 'medical building and room ventilation air conditioner': firstly, infection is prevented; secondly, protecting medical appliances; and thirdly, relevant occupational health and safety requirements. The purpose is to make the operating room environment sterile, but the means to make the sterility can be either passive or active. The measures of killing bacteria in indoor air by ultraviolet rays or killing the bacteria in the air by technologies such as ultraviolet rays and nano-technology and then sending the bacteria into the indoor air along with wind are all passive, and a large amount of bacterial corpses, metabolites and dust particles are remained in the indoor air and still remain harmful.

During long-term use, a lot of dust can be generated in the air conditioner, the dust provides nutrition for bacteria, and the bacteria (such as gram-negative bacteria, staphylococcus aureus, candida albicans, escherichia coli and the like) can be greatly propagated in the air conditioner to generate strange taste and can be sent to every corner of a room along with the circulation of air-conditioning airflow under the condition of proper temperature and humidity. And the air conditioner is integrated with a cooler, condensed water can be generated in the cooling process, bacteria have nutrient solution as long as the proper moisture exists, and the condensed water is an ideal breeding ground for the bacteria and the mould and can generate a biological film. The biological film is an ideal breeding ground for viruses, bacteria, molds and the like, and the bred bacteria and molds can enter a room along with the air supply system. Especially during the shut down, a large amount of bacteria and mold may grow, and when the air conditioner is restarted, the bacteria and mold may enter the room along with the air.

At present, the purification air conditioner in the operating room only adopts a blocking mode to block dust and bacteria outside a return air inlet and a fresh air inlet when the air conditioner is started, a large amount of bacteria and condensed water generated inside the air conditioner cannot be effectively treated when the air conditioner is stopped, and hidden dangers still exist when the air conditioner is started again. The operating room is a special application scene, and needs to be started before an operation and be stopped after the operation. Although the indoor air conditioner can be disinfected and cleaned when the air conditioner is stopped, the air conditioner cannot be disinfected. If the air conditioner is not cleaned for a long time, the clean air supply effect is greatly reduced, and the situations of postoperative infection of patients, medical instrument infection, medical staff infection and the like can be caused.
